Custom Windows Server 2012 R2 Images on Icehouse possible?

Hi there.
I've been following the install @ http://www.cloudbase.it/cloud-init-fo... and @ http://cloud-ninja.org/ to create my own Windows Server 2012 R2 image for OpenStack icehouse. I can get the image to boot but the VM is not accessible on the floating IP assigned to the instance. I can reach http://169.254.169.254 in a VM browser window. I have a standalone controller and neutron network node and my OpenStack setup is already running Centos and Ubuntu images successfully on a number of compute nodes.
